OIL BURNER.

Application filed March 21, 1925.

This invention relates to new and useful improvements in an oil burner.

()ne object of the invention is to provide a burner of the characterdescribed having a novel construction for vaporizing the fuel to beutilized.

Another object is to provide an oil burner of the character describedequipped with an air regulator whereby a proper mixture of air and fuelmay be, at all times, maintained, to induce the complete combustion ofthe fuel.

A further feature of the invention is to provide a burner of thecharacter described which may be readily taken apart for clean ing.

A. still further feature of the invention is to produce a burner of thecharacter described which is of simple construction and can be cheaplyand easily manufactured, and is economical and eflicient in use.

With the above and other objects in view, this invention has particularrelation to certain novel features of construction, operation andarrangement of parts an example of which is given in this specificationand illus trated in the accompanying drawings, where in Figure 1 is avertical sectional view of the burner.

Figure 2 is a perspective view, partly in section, and

Figure 3 is a cross section of the air reglr lator.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 designates the base of the burner. This base is preferably circular inform, and, as shown, has a central upstanding distributer 2, formedintegrally therewith, and provided to distribute, or film, the fuel,preparatory to the vaporization thereof.

Around this distributor the base is formed with an annular primer pan 3,having an overflow outlet 4. adapted to be connected with. a suitableoverflow line, (not shown).

Fitted over the distributor 2 there is a generator cap 5, provided withan annular hood-like rim 6, forming a flame spreader around its upperend. This cap is provided with an eye 7 to receive an implement forremoving itwhen it is desired to cleanse the same.

A fuel inlet duct 8 leads up through the Serial No. 17,374.

distributor and has its upper end cross grooved as at 9, and the fuelflows in through an inlet line, not shown, and passes up through theduct 8 and is distributed through the grooves 9 and flows in a film overthe distributer and between it and the cap 5. Vihen the fuel is firstadmitted, and before the burner becomes hot, the fuel will collect inthe primer pan 3 where it may be ignited. The flame will soon heat thegenerator cap and distributer and the film of oil flowing between themwill be converted into vapor which is readily combustible. The flamethereby generated will be: distributed throughout the combustion chamberof the stove, by the flame spreader 6.

In the preferred form of burner, as shown, the distributor is formedwith external, annular pockets 10, and the cap 5 is formed with inside,annular beads 11, conforming in shape to, and depending into, but spacedfrom the walls of the corresponding pockets 10. These pockets will fillwith the fuel and overflow, the fuel trickling down over and around theoutside of the distributor in a thin film all the way around, and theintermeshing beads, being relatively thin will. soon become very hotthus facilitating the vaporization of the fuel.

The base 1 is provided with a plurality, preferably four, of air inletopenings 12, arranged around the primer pan 3, and designed to permitthe upward passage of air to the mixing chamber 13, above said pan.Rotatably mounted on the base, there is an air regulator 14, which isannular in form and of hood like construction, with its outer wall 15resting on the outer margin of the base and its inner wall 16 resting onthe outer margin of the priming pan 3. Between the outer and inner wallsof this regulator there are thin partitions 17 which form the regulatorwith the air openings 18 corresponding in shape and position to the airopenings 12 of the base 1, said openings continuing on through the wall16 into said combustion chamber. When said openings 12 and 18 fullyregister a maximum amount of air is admitted through them to the flameto support combustion. By turning the regulator the supply of air may berestricted, to obtain the desired mixture, or completely out off.

What we claim is 1. A burner including a base, a distributer thereon,said base having an air inlet opening adjacent the distributer, agenerator cap fitted over the distributer and forming a fuel filmchannel between them, said burner having a fuel inlet duct terminatingin said channel, an annular air regulator on the base forming a mixingchamber between it and the cap into which said channel discharges fuel,said regulator having an air inlet opening adapted to be brought into,and out of, registration with the base opening to regulate the flow ofair into said chamber.

2. A burner including a base, a distributer thereon, said base having anair inlet adjacent the distributer, a generator cap fitted over thedistributer and forming a fuel film channel between them, said burnerhaving a fuel inlet duct terminating in said channel, an annular airregulator on the base forming a mixing chamber between it and the capinto which said channel discharges fuel, said regulator having an airopening adapted to be brought into, and out of, registration with theopening to regulate the flow of air into said chamber, and a primer paninto which the bottom of said chamber is formed.

3. A burner including a base, a distributer thereon, said base having anair inlet adjacent the distributer, a generator cap fitted over thedistributer and forming a fuel film channel between them, said burnerhaving a fuel inlet duct terminating in said channel, an annular airregulator on the base forming an annular mixing chamber between it andthe cap into Which said channel discharges fuel, said regulator havingan air opening adapted to be brought into, and out of, mg istration withthe opening to regulate the flow of air into said chamber, and a primerpan into which the bottom of said chamber is formed, said pan beingprovided with an overflow outlet.

in testimony whereof we have signed our names to this specification.
